What do fish and the fight against terrorism have in common, besides starting with the letter F? Well, how about this: the bluegill, or sunfish, a common freshwater dweller, is now being used in drinking water as a kind of a canary in a coal mine

Small numbers of the fish are kept in tanks constantly replenished with water from the municipal supply, and sensors in each tank work around the clock to register changes in the breathing, heartbeat and swimming patterns of the bluegills that occur in the presence of toxins.

I dunno, sort of makes you long for simpler times, like when I was 10 and a sunfish was merely something my dad and I threw back into the lake while waiting for a real catch.

Seems like we've got bigger fish to fry these days. Speaking of fish, if you're in a place where you can laugh out loud, check out this hilarious video of a man being attacked by the flying sort, over at ezprezzo.com.
